Brenda Wijaya Posted July 22, 2013 Report Share Posted July 22, 2013 Hi guys,Please help me answer:1. Is a ruler with measurement (eg. 15.1 cm) has a 0.1cm or 0.05cm uncertainty? I'm confused of which one is true. 2. Is an electronic balance with measurement (eg. 70.52 g) has a 0.01g or 0.005g uncertainty? HELP ME PLEASE! Thank you!
